The ease with which users can discover your features.
<aside> ℹ️ Discoverability means that the user can extract the knowledge they need of the product by looking at it. If the key elements to take action are well presented then discoverability is good.

Whenever we engage with an everyday thing such as a TV remote control, or a product like a website or an application, we figure out where and how to perform various functions. Through good discoverability, we can consider the different options and choose the one that should work to meet our goal. However, we cannot do this if the actions are not discoverable.
Norman describes good discoverability as: “it is possible to determine what actions are possible and the current state of the device.” Clear focal points (calls to action, images, and headers); visual hierarchy (content structured in order of priority); and transparent navigation systems all constitute good discoverability and understanding within a design.
However, when a design lacks discoverability, we must work harder to understand how something works. Take a website hamburger menu, for example; it is a convenient place to store multiple items, but it obscures key offerings and essential information.
